Product description

Why does the power bank charge fewer times than expected?

Some energy loss (typically 30 - 45%) is normal during power conversion because of battery and circuitry design. After conversion, a fully charged 20,100 mAh power bank provides about 11,250 mAh to your devices.

Why can't the power bank reach maximum power when recharging?

Make sure the cable supports 100W (5A). Third-party chargers only provide maximum power under the PD protocol. Heating during charging is normal. To protect the battery, power may drop. Charge in a cool area and avoid powering other devices.

Why does charging slow down or stop before my phone is fully charged?

iPhones may pause charging at 80% to protect battery health, especially when the phone becomes warm. Charging resumes after the phone cools down. Some phones also pause at 80% when battery optimization is enabled. Check your battery settings.

Is it normal for the power bank or connected devices to feel warm during charging?

Yes. Devices may warm up during long charging or when used for gaming or video. Metal casings can feel warmer because they dissipate heat more efficiently. Use the product in a cool, ventilated place (32 - 77°F / 0 - 25°C).

Why do the readings on the charger screen differ from those on a power bank or third-party tool such as POWER-Z?

Small display differences are normal.

Each device measures power in a different place, so results may vary.

Cable aging and transmission loss affect readings.

The power bank's display uses only one decimal place.
